- SMOKING-PIPE.

QQPECIPEGATION forming part of Letters Patent No. 341.150, dated May 4,1886.

Application filed April 29, 1884. Serial No. 129,704. (No model.)

To aZZ whom it may concern.-

Be it known that I, FERDINAND KUESTNER, of Brooklyn, county of Kings,and State of New York, have invented certain new and useful Improvementsin Smoking-Pipes, of which the following is a specification.

This invention has reference to an improved smokingpipe in which theonly substances containing nicotine are collected and prevented fromentering the stern of the pipe, and in which the parts composing thepipe are detachable, so as to be easily and thoroughly cleansed; and theinvention consists of apipebowl having a bottom opening and alongitndinally-perforated neck or socket communicating with saidopening, a pipe-stem fitted tightly into a seat at the upper end of thesocket, an extensiontube passing through the socket and provided with aslot facing the bottom opening of the bowl, and a screwcap attached tothe lower end of the extension-tube, whereby the stem is firmly securedto the bowl. v

In the accompanying drawings, Figure 1 represents a side elevation of myimproved smoking-pipe. Fig. 2 is a vertical central section of the same,and Fig. 3 is a detail view.

Similar letters of reference indicate corresponding parts.

A in the drawings represents the bowl of a sinoking-pipe,wl1ichisprovidedwithacover,a, and an opening, a, at the bottom of the bowl,connecting the inner space of the same with thelongitudinally-perlorated neck or socket B, that is made integral withthe body of the bowl and extended below and above the same. The upperend of this socket B has a tapering recess or seat, b, for thecorrespondingly tapering end of the stem 0. To the stem 0 is connected ametallic extension'tube, D, by a screw-thread at its upper end. Theextension-tube passes downward through the perforation of the socket B,and is retained in the same by a cap, E, screwed onto the lower threadedend of the tube D, whereby the lower end of the stem is pressed into thecor; responding recess, 1), of the socket B, so as to produce a tightfitting of the stem.

The extension-tube D is provided with aslot, (1, that is in line withthe bottom openinto said tube. By this arrangement the sediment is alsocollected outside of the tube D in the lower part of the socket B.

By unscrewing the screw-cap E,remov1ng the tube D, and unscrewing thestem 0 from the tube D, all the parts of the pipe can be easily andthoroughly cleansed.

As there is an annular air-space between the extension-tube D and thesocket B, the former is not heated up by contact with the surroundingparts of the socket and bowl; consequently the smoke is cooled inpassing through the extension-tube D to the stem 0, whereby smoking isrendered more agreeable.

I am aware that patents have been granted for pipes resembling mine inmany particulars; but none of these pipes show the annular space locatedin the bowl and the inner lining connected with the stem in the manner Ihave described and claimed.

Having thus described my invention, Iclaim as new and desire to secureby Letters Patent The combination of a pipe'bowl provided with a tubularneck open at both ends, said bowl and neck being connected bya duct, andthe upper end of said neck having a conical recess, a draft-tubescrew-threaded at both ends and provided with an intermediate slot, saiddraft-tube being of smaller diameter than the interior of saidneck,whereby an annular chamber is formed between them, a pi pe-stemhaving an interior screw-thread at its lower end and a conical exteriorsurface at said end, whereby it is adapted to fit the conical recess ofthe neck and connect with the screw FERDINAND KUESTN ER.
